Oritized genes whose expression variations had been most robust and tightly correlated with Purkinje cell survival in midline cerebellar sections. To accomplish this, we only incorporated genes whose expression was undetectable in 1 region of interest, and whose expression matched or was the inverse with the survival pattern in 20 week old Npc1 flox/-;Pcp2-Cre mice: robust in lobule X, patchy throughout the intermediate and posterior zones, with added sparing in the caudal aspect of lobule IX and a area spanning the caudal aspect of lobule VI and rostral lobule VII (Fig 1A). This yielded sixteen candidate neuroprotective or susceptibility genes (Fig 2A, Table 1); in situ hybridization photos from theFig 2. Candidate neuroprotective or pro-degenerative genes. (A) Hierarchical clustering of candidate genes, demonstrating robust differential expression involving regions of interest. Rows, genes; columns, person voxels within the regions of interest. Red designates greater and green designates decrease expression.

The GO Term Enrichment tool revealed considerable over-representation (p0.01) for GO terms containing Prkca, Prkcd, and Plcxd2, members with the phospholipase C–protein kinase C signal transduction cascade, suggesting that this pathway is differentially regulated between regions of interest. AmiGO was also utilized to query the complete list of GO Biological Approach terms connected with candidate genes. In assistance of our hypothesis that the differentially expressed genes would incorporate regulators of cellular survival and death choices, 5 genes had been connected with cell death connected annotations, such as “cell death” (GO:0008219, Dbc1 and Hspb1), “apoptosis” (GO:0006915, Pde1b and Prkcd), “negative regulation of apoptosis” (GO:0043066, Hspb1), and “induction of PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20051058 apoptosis by intracellular signals” (GO:0008629, Prkca). Moreover, the gene.
